Window blind system

Abstract

The present invention discloses a window blind system, comprising a shading arrangement and an alternating hanging device vertically extended downwardly to support a plurality of slats in position, wherein a predetermined portion of the slats are both supported by the first shading arrangement and the alternating hanging device, so that by operating the alternating hanging device, the predetermined portion of the slats supported by the alternating hanging device are capable of being displaced with respect to the remaining slats thus creating a varying shading effect.

AI Technical Summary

Benefits of technology

The system provides efficient control over sunlight intensity and privacy, matching conventional blinds in appearance and functionality while reducing assembly complexity and costs by using standardized components.

Problems solved by technology

When the blind is opened, sunlight can directly enter the window that not only heating up the interior of a house but also unpleasing to people's eye.

On the other hand, when the blind is fully closed, it blocks all the sunlight effectively.

Furthermore, the user has no privacy at all because the interior of the house is easily viewed from outside when the blind is opened, so that people may merely close the blind for privacy and security or open the blind for enjoying the sunlight.

In short, since the conventional window blind bears serious drawbacks, the users have to make a decision between sunshine and privacy.

However, this kind of amended duplex window blind are not compatible with standardized size of conventional window blinds.

This is unfortunate for those manufacturers as well as assembling workers since its assembling process is so awesome and laborious thus causing the production costs of this kind of multifunctional window blind rather high.
